OVERFLOW-VALVE FOR BATH-TUBS.

SPECIFICATION forming part of Letters Patent No. 770,344, dated September 20, 1904:.

Application filed February 1 1904.

To all whom itJw/cby concern:

Be it known that I, GEORGE M. VVEIGEL, a citizen of the United States, residing at Bal lard, in the county of King and State of WVashington, have invented certain new and useful Improvements in Overflow-Valves for Bath- Tubs, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to valves for bath-tub overflows; and it has for its object to provide a device of this character which shall be simple of construction, durable in use, and inexpensive of production and one by which the overflow-outlet may be quickly closed to prevent the escape of water thereat.

The invention consists in certain features of construction and combination of parts, which will be hereinafter more fully described.

In the accompanying drawings, Figure 1 is a vertical sectional view through the foot end of a bath-tub, illustrating the application of my invention; and Fig. 2 is a front View of the same.

Referring to the drawings, 2 denotes the end of the bath-tub, and 3 the L-shaped fitting commonly used to make connections between the tub at the outlet-aperture and the downflow-pipe 4E. The said fitting is provided with a transversely-arranged bridge-piece 5, through a screw-tapped hole 6 of which projects a similarly-screw-threaded bolt 7, whereby the operative parts, which I will now describe, are secured in place. These last-named parts comprise a stationary base-plate 8 and a rotatable sliding disk plate 9, contacting therewith. These plates are respectively provided with registering apertures 10 and 11,

concentrically arranged and having interme- Serial No. 191,488- (No model.)

diate closed portions, so that the plate 9 when partially rotated apertures 10 of the plate 8 may be covered up to prevent the egress of the water therethrough.

12 denotes a screw nut having integral therewith an axially-projecting cylindricalshaped projection 13, which is adapted to extend through and form an axle-bearing for the plate 9 and bear against the inner plate 8 to retain the latter fixedly in place. A washer 14: may advantageously be interposed between the hexagonal part of the nut and the plate 9 in order that the corners of the nut may not be engaged by the rotary plate, when the same at 16 and 17 can be made in any suitable manner, such as by gaskets 18.

The usefulness of the invention resides in the improved means for restraining the Water at will, whereby the depth thereof may be regulated so, as to submerge the body of an adult bather.

fhat I claim as new, and desire to secure by Letters Patent, is

The combination with the securing-bolt 7 of a circular plate 8 provided with perforations 10, a rotatable plate 9 provided with perforations 11 and adapted to be registered with the perforations 10, and anut 14: having a cylindrical projection 13 adapted to extend through an aperture 12 of plate 9 and bear against the plate 8, substantially as and for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE M. WEIGEL.
